Functional tests allow for the qualification and quantification of underlyi
ng function defects in the diagnosis of pelvic floor incompetence. However,
the results of these instrumental investigations alone do not suffice for
a therapeutic decision. The decision for a surgical therapy should therefor
e always be based on the clinical presentation, the extent of subjective im
pairment, and the degree of the causative pathophysiologic defect detected
in the function tests.
